Re: [xsl] Weird XPath evaluation differences between Saxon and Xalan

Provided the context is right, that should ensure that the text value of 
the preceding subtree is not the same as the text value of the preceding 
subtree. The context will have to be a node that has the GROUP nodes as 
siblings.

Many thanks for all those precisions. I learnt a difference between XSLT 
1.0 and 2.0 ! ;)

And I also learnt that the 2.0 version was only a draft... So I'd prefer 
to do my XPath query with the 1.0 version, but this query was used to 
compare two subtree of a XML file... So how can I get it working in XSLT 
1.0 ?

Can I do something like this ?

<xsl:variable name="lastTree">
  <xsl:for-each select="preceding-sibbling::GROUP[1]/SOMETHING/NAME">
    <xsl:value-of select="."/>
  </xsl:for-each>
</xsl:variable>

<xsl:variable name="currentTree">
  <xsl:for-each select="SOMETHING/NAME">
    <xsl:value-of select="."/>
  </xsl:for-each>
</xsl:variable>

<xsl:if test="$lastTree != $currentTree">
  <!-- Here I put my stuff -->
</xsl:if>

Many thanks for so precise answers. It looks like this list is a great 
place for finding XSLT experts ... :)
